Description

Die Erfindung bezieht sich auf einen Pflugkörper mit einem Streichblech in Vollkörper- oder in Streifenkörperausbildung, das mittels zumindest eines vorzugsweise am Streichblech angeklebten Befestigungselementes an einem Pflugtragkörper gehaltert ist.The invention relates to a plow body with a mouldboard in solid body or in striated body training, which is supported by means of at least one preferably adhered to the mouldboard fastener to a plow carrier body.

Ein Pflugkörper mit einem Streichblech der eingangs genannten Art ist aus der EP 1 586 229 B1 bekannt. Bei dem in diesem Dokument offenbarten Pflugkörper sind Streichbleche vorgesehen, die als Vollkörperbleche oder als Einzelstreichblechstreifen ausgebildet sein können und an einem Pflugtragkörper über jeweils ein Formelement festgelegt sind, das jeweils mit einer Vollfläche eines Streichbleches zu verkleben ist. Das Streichblech soll dabei eine homogene Einheit sein, das nicht durch Schrauben oder dergleichen Befestigungsmittel geschwächt ist. Das jeweilige Formelement hat zur weiteren Befestigung mit dem Pflugtragkörper jedoch eine Gewindebohrung oder eine in das Formelement eingelassene Senkschraube, so dass dieses mit dem Streichblech über die Schraubverbindung an dem Pflugtragkörper festzulegen ist.A plow body with a mouldboard of the type mentioned is from the EP 1 586 229 B1 known. In the plow body disclosed in this document mats are provided, which may be formed as Vollkörperbleche or as Einzelstreichblechstreifen and are fixed to a Pflugtragkörper each having a form member which is to be bonded in each case with a solid surface of a mouldboard. The mouldboard should be a homogeneous unit, which is not weakened by screws or the like fastener. However, the respective form element has for further attachment to the Pflugtragkörper a threaded hole or a recessed into the mold element countersunk screw so that it is set with the mouldboard on the screw on the plow carrier.

Da ein Streichblech in dem Bereich, in dem das Formelement mit dem Streichblech verklebt ist, einen erhöhten Verschleiß aufweist, ist dieses in diesem Bereich besonders hart ausgebildet. Durch die Verbindung des Formelementes mit dem Pflugtragkörper mittels der Schraubverbindung ist bei dieser Art der Befestigung jedoch eine keine Bewegung des Streichbleches zulassende, klapperfreie Befestigung des Streichbleches an dem Pflugtragkörper nicht möglich. Das gleiche gilt für in Aussparungen einzuhakende Hakenverbindungen, die alternativ in der Praxis bekannt geworden sind.Since a mouldboard in the region in which the mold element is glued to the mouldboard, has increased wear, this is particularly hard in this area. By connecting the mold element with the Pflugtragkörper by means of the screw, however, a no movement of the mouldboard permitting, rattle-free attachment of the mouldboard to the plow carrier is not possible in this type of attachment. The same applies to hooked in recesses hook connections that have become known alternatively in practice.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Pflugkörper der eingangs genannten Art mit möglichst geringem zusätzlichem Aufwand zu schaffen, bei dem eine möglichst keine freie Relativbewegung des Streichbleches zulassene Halterung eines eine große Härte aufweisenden Streichbleches am Pflugtragkörper ermöglicht ist.It is therefore an object of the present invention to provide a plow body of the type mentioned with the least possible additional effort, in which a possibly no free relative movement of the mouldable allow mounting of a high hardness mouldboard on Pflugtragkörper is possible.

Zur Lösung dieser Aufgabe zeichnet sich der Pflugkörper der eingangs genannten Art dadurch aus, dass das Befestigungsmittel einen Schwingungsdämpfer aufweist und dass das Streichblech unter Zwischenlage dieses Schwingungsdämpfers an dem Pflugtragkörper festgelegt ist. Damit ist das Streichblech über eine Art der Befestigung am Pflugtragkörper festzulegen, die keine freien Relativbewegungen zwischen Streichblech und Pflugtragkörper auch bei höheren Pfluggeschwindigkeiten und damit größerer Beanspruchung zulässt. Damit ist eine verschleißarme und somit auch klapperfreie Halterung des Streichbleches an dem Pflugtragkörper möglich, wobei diese Vorteile sich gleichermaßen bei Streichblechen auswirken, die als Vollstreichbleche oder als Einzelstreichblechstreifen ausgebildet sind.To solve this problem, the plow body of the aforementioned type is characterized in that the fastening means comprises a vibration damper and that the mouldboard is fixed with the interposition of this vibration damper on the plow support body. Thus, the mouldboard on a type of attachment to the plow support body is set, which does not allow free relative movement between mouldboard and Pflugtragkörper even at higher plow speeds and thus greater stress. Thus, a low-wear and thus rattle-free mounting of the mouldboard on the plow carrier is possible, these advantages are equally affect mouldboard, which are designed as Vollstreichbleche or as a single matte strips.

Der Schwingungsdämpfer ist ein relativ einfach bauendes Bauteil und kann mit einem nur geringen Montageaufwand bei der Befestigung des jeweiligen Streichbleches vorgesehen sein. So bieten sich bereits als Schwingungsdämpfer einfache Federelemente an, die z.B. unter der Mutter einer Schraubverbindung angeordnet werden. Ebenfalls ist es möglich, z.B. Zwischenschichten aus einem elastischen Material bei der Befestigung vorzusehen oder auch beispielsweise federnde Blöcke, die aus einem elastischen Material bestehen und die beispielsweise ein Anschlussteil aufnehmen, das Teil des Befestigungselementes ist.The vibration damper is a relatively simple component and can be provided with only a small installation effort in the attachment of the respective mouldboard. Thus, even as a vibration damper simple spring elements, which are arranged for example under the nut of a screw. It is also possible, for example to provide intermediate layers of an elastic material in the attachment or even, for example, resilient blocks, which consist of an elastic material and which, for example, receive a connection part which is part of the fastening element.

Solche Ausgestaltungen der Befestigungsvarianten sind Gegenstand von Unteransprüchen als Weiterbildungen der vorliegenden Erfindung, auf die hiermit ausdrücklich verwiesen wird. Diese sind auch in den zeichnerischen Beispielen noch näher veranschaulicht.Such embodiments of the mounting variants are the subject of subclaims as developments of the present invention, to which expressly incorporated herein by reference.
